DAMPING DEVICE FOR MUSIC-BOXES.

SPECIFICATION forming part of Letters Patent No. 417,650, dated December17, 1889.

Application filed May 27, 1889. Serial No. 312,201. (No model.)

To all whom it may concern:

Be it known that I, OSKAR PAUL LOOHMANN, a subject of the King ofPrussia and Emperor of Germany, residing at Gohlis, near Leipsic,

in the Kingdom of Saxony, Germany, have invented new and usefulImprovements in Damping Devices for Music-Boxes, of which the followingis a specification.

This invention relates to a damping device for music-boxes having reedsor tongues vibrated by a star-wheel.

The invention consists in the various features of improvement more fullypointed out in the claim.

In the accompanying drawings, Figures 1, 3, and 5 are sectional faceviews of my improved damping device, showing the same in differentpositions. Figs. 2, 4, and 6 are end views of Figs. 1, 3, and 5,respectively.

The letter 2 represents a reed attached to support 2. The free end ofreed zis vibrated by a star-wheel b, the teeth I II III, &c., of whichmomentarily depress the reed upon the revolution of the star-wheel.

c is a spring-damper secured to support 0 and adapted to come intocontact at its free end with reed z. The damper c has an in-.wardly-bent projection or shoulder c placed in the path of thestar-wheel Z).

The operation of the device is as follows:

\Vhile one of the teeth of wheel I) vibrates reed a the succeeding toothbears against shoulder c and holds the damper away from the reed. Fig. 1shows the tooth I immediately after it has vibrated reed ,2, while toothII holds off the damper. After tooth II has cleared shoulder c thedampercleans against the reed and softens the sound before the reed isstruck by tooth II. This position is shown in Fig. 3. Shortly beforetooth II comes into contact with the reed the damper is raised by toothIII, so that the reed may vibrate freely when being struck by tooth II.Fig. 5 shows the position of the parts when the reed is vibrated bytooth II. By the above-described arrangement the reed is alternatelyliberated and engaged by the damper as the wheel is revolved.

WVhat I claim is The combination of vibrating reed z with vibratingspring-damper 0, having shoulder 0 and with the star-wheel 12,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

OSKAR PAUL LOCHMANN.
